Description

Technical Field

[0001] This invention relates to the field of drying and pulverizing technology, and in particular to a drying and pulverizing device for processing Codonopsis pilosula. Background Technology

[0002] As a traditional Chinese medicine, the pulverization process before use is crucial for maximizing the efficacy of Codonopsis pilosula. Current pulverization methods mostly rely on a cutting blade structure, but these methods suffer from problems such as poor pulverization effect and limited functionality, as detailed below: I. Limited Crushing Methods, Making it Difficult to Achieve Ideal Fineness in One Batch: Current methods for crushing Codonopsis pilosula mostly employ a single processing mechanism, which cannot achieve the target particle size requirement through a single crushing process. Repeated processing of the initially crushed material is necessary. This process easily leads to over-crushing of some Codonopsis pilosula. II. Insufficient Particle Size Adaptability of Codonopsis pilosula: The particle size of Codonopsis pilosula directly affects the efficacy release efficiency, processing feasibility, and product form. Different uses correspond to specific particle size standards: coarse powder (2-4 mm) is suitable for soups and decoctions, retaining some fiber structure, allowing for slow and complete release of efficacy during stewing, while also facilitating filtration to separate dregs and prevent turbidity in the broth; fine powder (0.5-1 mm) is used for the preparation of compound Chinese medicine granules and capsule filling, requiring uniform particle size and good flowability to ensure full dissolution of efficacy and precise dosage control. However, existing equipment can only meet the processing requirements of a single particle size and cannot adapt to multiple scenarios, resulting in significant functional limitations.

[0003] To address these issues, we designed a drying and pulverizing device for processing Party ginseng. Summary of the Invention

[0004] In response to the above situation and to overcome the defects of existing technology, this invention provides a drying and pulverizing device for processing Codonopsis pilosula. First, it uses a filter screen to screen the particle size of the pulverized Codonopsis pilosula, and recycles any substandard material for secondary pulverization to ensure that the final product particle size meets the set standard. Second, it uses an adjustment component to flexibly switch the flow direction of the pulverized Codonopsis pilosula, enabling three processing modes as needed: separate coarse powder processing, separate fine powder processing, and simultaneous coarse and fine powder processing, adapting to various production scenarios.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A drying and pulverizing device for processing party ginseng, comprising a pulverizing box, a conveying mechanism, a pulverizing mechanism, a hot air blower, and a collection box; The two grinding boxes are connected in series and are respectively connected to the two collection boxes, and are used to process Codonopsis pilosula into coarse and fine powder respectively. Each grinding box has a partition and a filter screen. The partition and the bottom surface of the grinding box form a circular cavity, which, together with the top surface, forms a return channel. Several cutting blades are installed inside the circular cavity. A return port is opened towards the filter screen, and a guide plate covers the return port. The end face of the grinding box processing coarse powder has a first opening and a second opening, which are respectively connected to the grinding box processing fine powder and the connected collection box. A conveying mechanism is used to transport Codonopsis pilosula into the grinding boxes. The crushing mechanism consists of a servo motor, a drive shaft, a cutting blade assembly, a sweeping plate, and an adjustment assembly; the drive shaft passes through the two crushing chambers; the two cutting blade assemblies are respectively placed inside the two crushing chambers; the two sweeping plates are attached to the two filter screens; the adjustment assembly is set in the crushing chamber for processing coarse powder and is used to open or close the first opening and the second opening; the hot air blower is connected to the two return channels through two pipes respectively, and an electric valve is installed on one of the pipes.

[0006] In one embodiment, the conveying mechanism comprises a conveying pipe, a spiral conveying rod, and a hopper; one end of the conveying pipe extends into the crushing chamber and has an outlet located in the circular cavity of the crushing chamber, while the other end is connected to the hopper, and the spiral conveying rod is built into the conveying pipe.

[0007] In one embodiment, the spacing between the spiral blades of the spiral transmission rod is less than the length of Codonopsis pilosula, and the edges of the spiral blades are designed with a sharp structure, so that the Codonopsis pilosula is cut into pieces simultaneously during the transmission process.

[0008] In one embodiment, the adjustment assembly comprises a bushing, a first protrusion, a baffle, a second protrusion, a slip ring, a lever, a spring, and a housing. The bushing is fixed to the end of the crushing chamber. The semi-circular baffle is rotatably connected to the bushing by an interference fit. Four second protrusions are equidistantly distributed along the axis on its surface, and one side of each second protrusion is a slope. Three first protrusions are correspondingly provided on the bushing. Both sides of each first protrusion are sloped and they are arranged opposite to the second protrusions, forming a gap due to the difference in their numbers. The slip ring is horizontally slidably mounted on the drive shaft, and a lever is fixed on it. The housing completely encloses the bushing, the first protrusion, and the second protrusion. A spring is installed between the slip ring and the housing.

[0009] In one embodiment, when the servo motor drives the drive shaft to rotate slowly clockwise, the slip ring rotates synchronously with the drive shaft. When the lever rotates to the neutral area, it will push the second protrusion in that area to rotate the baffle. When the second protrusion in the neutral area rotates 90 degrees, the slope of the first protrusion will push the slip ring to slide axially through the lever, causing the lever to separate from the second protrusion. During this process, the baffle completes a 90-degree rotation, at which point the baffle blocks the second opening. Each time the lever rotates one revolution with the drive shaft, it can drive the baffle to complete one 90-degree rotation. The servo motor rotates counterclockwise at high speed to process the Codonopsis pilosula into powder.

[0010] In one embodiment, after the baffle rotates, it can individually block the first opening and the second opening, while simultaneously opening the first and second openings, i.e., switching between coarse powder processing mode, fine powder processing mode, and simultaneous coarse and fine powder processing mode.

[0011] In one embodiment, the side of the baffle facing the filter screen has a sloping structure.

[0012] In one embodiment, the top cover of the collection box has multiple air vents, and the multiple air vents are covered with a non-woven fabric layer.

[0013] In one embodiment, when it is necessary to process Codonopsis pilosula into fine powder, the electric valve is opened and the power of the hot air blower is increased.

[0014] In one embodiment, the number of cutting blades and cutting blades in the grinding chamber for processing fine powder is greater than that in the grinding chamber for processing coarse powder.

[0015] The beneficial effects of this invention are as follows: (1) The present invention first cuts Codonopsis pilosula into blocks through a conveying mechanism. The material enters the first crushing chamber to complete the coarse powder processing, and then is conveyed to the second crushing chamber for fine powder processing, thereby realizing graded crushing operation. At the same time, Codonopsis pilosula powder that does not reach the preset precision can re-enter the chamber through the return channel for secondary crushing, ensuring that the particle size of the final product meets the set standard.

[0016] (2) The present invention adjusts the connection state between the first crushing chamber, the second crushing chamber, and the collection box by adjusting the adjustment group, and can flexibly switch between three modes: coarse powder processing, fine powder processing, and simultaneous coarse and fine powder processing, to meet diverse production needs.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0019] Please see Figure 1-2 The present invention provides a drying and pulverizing device for processing Codonopsis pilosula, comprising: a pulverizing box 1, a conveying mechanism 2, a pulverizing mechanism 3, a hot air blower 4, and a collecting box 5; Please see Figure 1-2The grinding chamber 1 consists of two chambers, namely a first grinding chamber 11 and a second grinding chamber 12, arranged in series. The first grinding chamber 11 is responsible for initially processing the Codonopsis pilosula into coarse powder, while the second grinding chamber 12 is responsible for further processing it into fine powder. The conveying mechanism 2 has both conveying and cutting functions. During the process of conveying the Codonopsis pilosula to the first grinding chamber 11, it simultaneously completes the cutting process. After being cut into pieces, the Codonopsis pilosula first enters the first grinding chamber 11 to be made into coarse powder. If a higher precision fine powder is required, the coarse powder can then enter the second grinding chamber 12 for secondary processing. The grinding mechanism 3 undertakes the core grinding operation, grinding the Codonopsis pilosula in the first grinding chamber 11 and the second grinding chamber 12, while controlling the communication between the first grinding chamber 11 and the second grinding chamber 12. The hot air blower 4 introduces hot airflow into the first grinding chamber 11 and the second grinding chamber 12. Two collection boxes 5 are respectively connected to the first grinding chamber 11 and the second grinding chamber 12 to collect Codonopsis pilosula products with different grinding precision. Please see Figure 3 The internal structure of the first grinding chamber 11 and the second grinding chamber 12 is the same. The first grinding chamber 11 will be used as an example for explanation. The first grinding chamber 11 is provided with a partition 13. The partition 13 and the bottom surface of the first grinding chamber 11 form a circular cavity. Several cutting blades 14 are arranged along the axis inside the circular cavity. One end of the circular cavity is directly opposite the filter screen 16. A return port 15 is opened above the end of the circular cavity facing the filter screen 16. A guide plate 150 is covered above the return port 15. The partition 13 and the top surface of the first grinding chamber 11 together form a return channel. Please see Figure 4 The first crushing chamber 11 has a first opening 111 and a second opening 112 on the end face facing the second crushing chamber 12, and the two are combined to form a semi-circular structure; wherein the first opening 111 is used to communicate with the collection box 5, and the second opening 112 is used to communicate with the second crushing chamber 12. Please see Figure 5 The conveying mechanism 2 comprises a conveying pipe 21, a spiral conveying rod 22, and a hopper 23. One end of the conveying pipe 21 extends into the first crushing chamber 11, and an outlet is provided at this end, which is located within the circular cavity of the first crushing chamber 11. The other end is connected to the hopper 23. The spiral conveying rod 22 is built into the conveying pipe 21 and is driven by a motor to rotate. Since the spacing between the spiral blades of the spiral conveying rod 22 is less than the length of the Codonopsis pilosula, and the edges of the spiral blades are designed with a sharp structure, the Codonopsis pilosula is cut into pieces simultaneously during the conveying process. The specific working process is as follows: after the Codonopsis pilosula enters the conveying pipe 21 from the hopper 23, it is cut into pieces and conveyed by the spiral conveying rod 22, and finally sent into the first crushing chamber 11 through the outlet. Please see Figure 6The crushing mechanism 3 consists of a servo motor 30, a drive shaft 31, a cutting blade assembly 32, a sweeping plate 33, and an adjustment assembly 34. The drive shaft 31 passes through the first crushing chamber 11 and the second crushing chamber 12, and is powered by the servo motor 30. The two sets of cutting blade assemblies 32 are fixed on the drive shaft 31 and are respectively placed inside the circular cavities of the first crushing chamber 11 and the second crushing chamber 12. The second crushing chamber 12 has more blades of the cutting blade assembly 32 and the cutting blade 14 than the first crushing chamber 11, thereby achieving fine crushing of Codonopsis pilosula. The two sets of sweeping plates 33 are also fixed on the drive shaft 31. It maintains a close fit with the filter screen 16 of the first grinding chamber 11 and the second grinding chamber 12; when the sweeping plate 33 rotates at high speed with the drive shaft 31, it can sweep away the Codonopsis powder that has not passed through the filter screen 16, and push the Codonopsis powder to the return port 15 with the help of centrifugal force; the adjustment group 34 is set in the first grinding chamber 11, located between the filter screen 16 and the first grinding chamber 11. The adjustment group 34 is used to control the communication state between the first grinding chamber 11, the second grinding chamber 12, and the collection box 5. The processing mode of Codonopsis can be switched through the adjustment group 34, namely, coarse powder processing mode, fine powder processing mode, and coarse and fine powder simultaneous processing mode; Please see Figure 7 The adjustment assembly 34 consists of a bushing 341, a first protrusion 342, a baffle 343, a second protrusion 344, a slip ring 345, a lever 346, a spring 347, and a housing 348. The bushing 341 is fixed to the end of the first crushing chamber 11. The semi-circular baffle 343 is rotatably connected to the bushing 341 by an interference fit, which can prevent the baffle 343 from rotating arbitrarily. The side of the baffle 343 facing the filter screen 16 has a sloping structure, and four second protrusions 344 are evenly distributed along the axis on its surface, with one side of each second protrusion 344 being a slope. Three first protrusions 342 are correspondingly arranged on the bushing 341. Both sides of the first protrusions 342 are sloped and are arranged opposite to the second protrusions 344, with the difference in their numbers forming a gap area. The slip ring 345 is horizontally slidably mounted on the drive shaft. On 31, a lever 346 is fixedly mounted; the outer casing 348 completely encloses the bushing 341, the first protrusion 342, and the second protrusion 344 to prevent the Codonopsis pilosula powder from adhering and causing jamming; a spring 347 is installed between the slip ring 345 and the outer casing 348 for the reset of the slip ring 345; when the servo motor 30 drives the transmission shaft 31 to rotate slowly clockwise, the slip ring 345 rotates synchronously with the transmission shaft 31. When the lever 346 rotates to the neutral area, it will push the second protrusion 344 in that area to drive the baffle 343 to rotate; when the second protrusion 344 in the neutral area rotates ninety degrees, the slope of the first protrusion 342 will push the slip ring 345 to slide axially through the lever 346, causing the lever 346 to separate from the second protrusion 344. During this process, the baffle 343 completes a ninety-degree rotation. Please refer to Figure 8At this time, the baffle 343 blocks the second opening 112, and the equipment switches to coarse powder processing mode; the lever 346 rotates one revolution with the drive shaft 31, which drives the baffle 343 to complete one 90-degree rotation; the servo motor 30 rotates counterclockwise at high speed to process the Codonopsis pilosula into powder, and the hot airflow pushes the powdered Codonopsis pilosula along the filter screen 16 and the first opening 111 into the collection box 5. The purpose of setting one side of the baffle 343 as a slope is to guide the powdered Codonopsis pilosula to move to the first opening 111; Please see Figure 1 , 2 5. The hot air blower 4 is connected to the return channels of the first crushing chamber 11 and the second crushing chamber 12 via two pipes 41, respectively. An electric valve 42 is installed on the pipe 41 connecting to the second crushing chamber 12 to regulate the supply of hot air to that chamber. The hot air output by the hot air blower 4 has a dual function: firstly, it directly acts on the Codonopsis pilosula material to achieve drying; secondly, it flows directionally along the return channel. When it flows through the guide plate 150 area, a negative pressure area is formed at the return port 15 due to the combined influence of the channel structure and the airflow velocity. The directional adsorption force generated by this negative pressure can accurately adsorb Codonopsis pilosula powder in the circular cavity that has not reached the preset precision, allowing it to re-enter the cavity through the return port 15 for secondary crushing, thus ensuring the uniformity of the Codonopsis pilosula powder particle size. Simultaneously, the flow force of the hot air can push the blocky Codonopsis pilosula sent through the conveying pipe 21, allowing it to smoothly enter the circular cavity for crushing. Please see Figure 9 The upper cover of the collection box 5 has multiple air outlets 51, and the multiple air outlets 51 are covered with a non-woven fabric layer, which prevents the powdered Codonopsis pilosula from moving out of the collection box 5 with the hot air flow.

[0020] Working principle of this invention: In the coarse powder processing mode, the servo motor 30 drives the transmission shaft 31 to rotate counterclockwise at high speed, which drives the cutting blade assembly in the first crushing chamber 11 to process Codonopsis pilosula into powder. The hot airflow pushes qualified powder through the filter screen 16 and flows into the corresponding collection box 5 through the first opening 111. Powder that does not meet the preset precision is adsorbed by the negative pressure at the return port 15 and re-enters the circular cavity for secondary crushing. During this process, the slip ring 345 rotates counterclockwise at high speed synchronously with the transmission shaft 31, and the lever 346 only slides along the slope of the first protrusion 342 and the second protrusion 344, without applying rotational power to the baffle 343.

[0021] Please see Figure 10As shown in Figure A, in the fine powder processing mode, the servo motor 30 rotates slowly clockwise for two revolutions, causing the baffle 343 to rotate 180 degrees, completely blocking the first opening 111; at the same time, the electric valve 42 opens the pipe 41 of the second grinding chamber 12, and the hot air blower 4 increases its output power; the Codonopsis powder in the first grinding chamber 11 is pushed by the hot airflow, passes through the filter screen 16, and enters the second grinding chamber 12 through the second opening 112 for fine processing; the powder in both grinding chambers that does not meet the precision requirements is returned to the reflux port 15 for pulverization, and finally the qualified fine powder flows into the corresponding collection box 5 to complete the collection.

[0022] Please see Figure 10 As shown in Figure B, the servo motor 30 rotates slowly clockwise for one revolution, driving the baffle 343 to rotate 90 degrees, so that the first opening 111 and the second opening 112 are simultaneously in the open state; the coarse powder processed by the first crushing chamber 11 and the fine powder processed by the second crushing chamber 12 flow into the two collection boxes 5 respectively, realizing the synchronous processing and classified collection of coarse and fine powders.

[0023] The above embodiments are merely one of the preferred embodiments of the present invention and should not be used to limit the scope of protection of the present invention. Any modifications or refinements made to the main design concept and spirit of the present invention that are not of substantial significance, but solve the same technical problem as the present invention, should be included within the scope of protection of the present invention.
